[0002] In the current booming automobile industry, the importance of the field of manufacturing automotive interior parts is increasingly prominent. Automotive interior parts not only concern the aesthetics and comfort of the automobile, but also directly affect the driving experience of consumers. Among them, the manufacturing process and quality standards of automobile seat accessories, as a key component of interior parts, are of great concern. The quality of seat accessories not only determines the overall performance and service life of the seat, but also is closely related to the safety and comfort of passengers. As the core tool in the production process of automobile seat accessories, the performance of the stamping die directly determines the quality and production efficiency of the product. An efficient and accurate stamping die can ensure the dimensional accuracy and surface quality of the seat accessories, meet the strict requirements of automobile manufacturing, and thus improve the market competitiveness of the entire automobile product.

Due to the instantaneous release of the impact force, the noise level is very high, and the sound produced is very loud. Long-term exposure to such a high-noise working environment not only seriously damages the acoustic environment of the workplace, affects the work mood and communication efficiency of the operators, but also can cause irreversible damage to the hearing of the operators, causing hearing loss, tinnitus and other health problems, and posing a great threat to the physical and mental health of the operators.

DETAILED DESCRIPTION

[0039] The application is described in further detail below with reference to the drawings. Figures 1-11 The application is described in further detail below with reference to the drawings.

[0040] The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. Unless otherwise defined, technical or scientific terms used in the present application shall have the same meaning as is commonly understood by one of ordinary skill in the art to which this application belongs. The use of the terms "first", "second" and similar terms in the present application do not denote any order, quantity, or importance, but are used to distinguish one element from another.

[0041] For the convenience of understanding, in the horizontal direction in the present embodiment, the length direction of the die structure is defined as the first direction, and the width direction of the die structure is defined as the second direction, and the left rear seat right side armrest support stamping die structure is described on this basis.

[0042] The present application discloses a left rear seat right side armrest support stamping die structure. Referring to Figure 1 , the left rear seat right side armrest support stamping die structure comprises an upper die 2 and a lower die 3. The first punching mechanism 4, the second punching mechanism 5, the initial bending mechanism 6, the bending and punching mechanism 7, the two side bending mechanisms 8, the drilling mechanism 9 and the cutting mechanism 10 are sequentially arranged between the upper die 2 and the lower die 3 along the length direction of the die structure.

[0043] The upper die 2 comprises a top plate 21 and an upper die plate 22, and the upper die plate 22 is fixed to the lower surface of the top plate 21. The lower die 3 comprises a bottom plate 31, a support seat 32 and a lower die plate 33, the support seat 32 is fixed to the upper surface of the bottom plate 31, and the lower die plate 33 is fixed to the upper surface of the support seat 32. In the vertical direction, the upper die plate 22 and the lower die plate 33 are aligned to ensure the accurate fit of the upper and lower dies 3 during stamping and improve the stamping precision.

[0044] Referring to Figure 1 , Figure 2 and Figure 3 , the lower surface of the upper die plate 22 is sequentially fixed with the first upper mounting seat 23 and the second upper mounting seat 24 along the length direction of the die structure, and the end of the first upper mounting seat 23 abuts against the end of the second upper mounting seat 24 to ensure the stability of the die structure and the continuity of the stamping process. The upper surface of the lower die plate 33 is sequentially fixed with the lower mounting seat 34 along the length direction of the die structure.

[0045] Referring to Figure 2 and Figure 3Specifically, the first punching mechanism 4 includes an intermediate punch 41 and a first end punch 42, both of which are fixed on the mounting seat and protrude from the lower surface of the first upper mounting seat 23. The intermediate punch 41 and the first end punch 42 protrude from the first upper mounting seat 23 to different heights, and the bottom ends of the intermediate punch 41 and the first end punch 42 are provided with grooves of different shapes. In terms of arrangement, the intermediate punch 41 and the first end punch 42 are distributed along the second direction, so that during the punching process, the intermediate punch 41 and the first end punch 42 do not collide with the material belt at the same time, but contact the material belt in a certain order, thereby avoiding the one-time and synchronous impact force generated by all punches, effectively reducing the noise generated during the punching process, improving the acoustic environment of the workplace, ensuring the working mood and communication efficiency of the operators, and avoiding irreversible damage to the hearing of the operators caused by high noise, protecting the physical and mental health of the operators.

[0046] With reference to Figure 2 and Figure 3 From the perspective of shape adaptation, the shape of the first end punch 42 matches the shape of the first end isolation hole 12, and the shape of the intermediate punch 41 matches the shape of the intermediate isolation hole 11. The lower mounting seat 34 is provided with a through intermediate punch hole 341 and a first end punch hole 342, wherein the intermediate punch hole 341 is located directly below the intermediate punch 41 and can slide with the intermediate punch 41, and the first end punch hole 342 is located directly below the first end punch 42 and can slide with the first end punch 42.

[0047] With reference to Figure 3 , Figure 4 and Figure 5 When the first punching mechanism 4 starts working, under the driving action of the punch, the first upper mounting seat 23 drives the intermediate punch 41 and the first end punch 42 to move downward together. During the pressing process, the intermediate punch 41 will pass through the material belt 1 and cut out the intermediate isolation hole 11 on the material belt 1 under the cooperation of the intermediate punch hole 341 of the lower mounting seat 34; the first end punch 42 will pass through the material belt 1 and cut out the first end isolation hole 12 on the material belt 1 under the cooperation of the first end punch hole 342 of the lower mounting seat 34.

[0048] With reference to Figure 3 and Figure 4The upper surface of the lower die plate 33 is provided with a through intermediate blanking hole 331 and a first end blanking hole 332. The intermediate blanking hole 331 is directly below the intermediate punching hole 341 and aligned with the same. The first end blanking hole 332 is directly below the first end punching hole 342 and aligned with the same. In addition, the bottom plate 31 of the lower die 3 is provided with a first belt assembly 35. The intermediate blanking hole 331 and the first end blanking hole 332 are directly above the first belt assembly 35, which facilitates the conveying of waste. The waste punched out will fall through the intermediate blanking hole 331 and the first end blanking hole 332. Since the intermediate blanking hole 331 is aligned with the intermediate punching hole 341, the waste can fall smoothly, avoiding the situation of being blocked in the mold. The falling waste will directly fall onto the first belt assembly 35 directly below, which will convey the waste generated by the first punching mechanism 4 along the second direction, thereby completing the entire punching and waste processing process.

[0049] With reference to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the second punching mechanism 5 includes a through punch 51 fixedly installed on the lower surface of the first upper mounting seat 23 and protruding from the lower surface of the first upper mounting seat 23. Its function is to cut the first interval isolation hole 13 on the material belt 1. The surface of the lower mounting seat 34 is provided with a through first through punching hole 343. The shape of the first through punching hole 343 is matched with the shape of the through punch 51, and the two can be slidably connected to ensure the smooth progress of the punching process. The upper surface of the lower die plate 33 is also provided with a through through blanking hole 333, which is accurately located directly below the first through punching hole 343 and communicates with the first through punching hole 343, providing a falling channel for the waste punched out.

[0050] With reference to Figure 2 , Figure 3 and Figure 4 When the second punching mechanism 5 starts to work, the first upper mounting seat 23 drives the through punch 51 to move downward under the action of the driving device. Since the through punch 51 is slidably connected with the first through punching hole 343 on the lower mounting seat 34, and the shape of the first through punching hole 343 is matched with that of the through punch 51, the through punch 51 will pass through the material belt 1 to cut the first interval isolation hole 13 on the material belt 1. The first interval isolation hole 13 is located between the first end isolation hole 12 and the intermediate isolation hole 11, and one end is in communication with the first end isolation hole 12 and the other end is in communication with the intermediate isolation hole 11.

[0051] With reference to Figure 2 , Figure 3 , Figure 4 and Figure 5Since the upper surface of the bottom plate 31 is provided with the first belt assembly 35, and the first belt assembly 35 is located directly below the communication blanking hole 333, it is used to convey the waste produced by the second punching mechanism 5 in the second direction. At the same time, the first blanking rail 36 is fixedly arranged on the support seat 32. The first blanking rail 36 is arranged in an inclined manner, the top end of which is located directly below the communication blanking hole 333, and the bottom end of which is located directly above the first belt assembly 35, so as to facilitate the smooth sliding of the waste. The waste produced in the punching process will fall through the communication blanking hole 333 on the lower die plate 33. Because the top end of the first blanking rail 36 is located directly below the communication blanking hole 333, the waste will first fall into the first blanking rail 36. Since the first blanking rail 36 is arranged in an inclined manner, the waste will slide along the inclined surface of the first blanking rail 36 to the bottom end. Since the bottom end of the first blanking rail 36 is located directly above the first belt assembly 35, the waste will eventually fall onto the first belt assembly 35. This ensures that the waste produced by the second punching mechanism 5 can be conveyed away by the first belt assembly 35, avoiding the accumulation of waste affecting the normal operation of the mechanism, and ensuring the efficient and stable operation of the entire punching process.

[0052] With reference to Figure 2 The initial bending mechanism 6 includes a first upper bending seat 61 and a first lower bending seat 62. The first upper bending seat 61 is fixed to the lower surface of the first upper mounting seat 23, and the first lower bending seat 62 is fixed to the upper surface of the lower mounting seat 34, and the first lower bending seat 62 is located directly below the first upper bending seat 61. Such a layout ensures the accuracy of the bending process. The lower surface of the first upper bending seat 61 is curved, and the lower surface of the first upper bending seat 61 is integrally formed with a first upper bending convex strip 611. Meanwhile, the lower surface of the first upper bending seat 61 is also provided with a first upper bending recess 612. The first upper bending convex strip 611 and the first upper bending recess 612 are also curved structures, and one end of the first upper bending convex strip 611 is located in the first upper bending recess 612.

[0053] With reference to Figure 3 Correspondingly, the upper surface of the first lower bending seat 62 is also a curved structure, and the upper surface of the first lower bending seat 62 is provided with a first lower bending recess 621. The shape of the first lower bending recess 621 is matched with the shape of the first upper bending convex strip 611. The upper surface of the first lower bending seat 62 is also integrally formed with a first lower bending convex 622, and the shape of the first lower bending convex 622 is matched with the shape of the first upper bending recess 612. This makes the bending process form a complex curved shape, meeting the bending requirements of the fittings. Thus, it is convenient to stamp out the basic shape of the workpiece.

[0054] With reference to Figure 2 and Figure 3When the initial bending mechanism 6 starts to work, the first upper mounting seat 23 drives the first upper bending seat 61 to move downward, gradually approaching the first lower bending seat 62. With the descent of the first upper bending seat 61, the first upper bending convex strip 611 on its lower surface will be inserted into the first lower bending concave groove 621 on the upper surface of the first lower bending seat 62, while the first lower bending convex 622 on the upper surface of the first lower bending seat 62 will enter the first upper bending concave groove 612 on the lower surface of the first upper bending seat 61. In this process, since the upper and lower seat surfaces are both curved structures, and the convex strip and the concave groove are matched with each other, under the action of pressure, the workpiece placed between the first upper bending seat 61 and the first lower bending seat 62 will be extruded and shaped. The cooperation of the first upper bending convex strip 611 and the first lower bending concave groove 621, as well as the cooperation of the first lower bending convex 622 and the first upper bending concave groove 612, enables the workpiece to be bent according to the preset shape, forming a complex curved surface shape, thereby meeting the bending requirements of the accessory and facilitating the stamping out of the basic shape of the workpiece. The entire bending process relies on the precise cooperation of the upper and lower seats and the unique curved structure to ensure the quality and precision of the bending With reference to Figure 2 and Figure 3 , the bending and punching mechanism 7 includes a second upper bending seat 71 and a second lower bending seat 72, the second upper bending seat 71 is fixed to the lower surface of the second upper mounting seat 24, and the second lower bending seat 72 is fixed to the upper surface of the lower die plate 33. The lower surface of the second upper bending seat 71 and the upper surface of the second lower bending seat 72 are both curved surfaces, so that further bending of the workpiece can be achieved.

[0055] With reference to Figure 2 , Figure 3 and Figure 4 , the lower surface of the second upper bending seat 71 is fixedly provided with a second end portion punch 73, and the second lower bending seat 72 is provided with a second end portion punch hole 77 that penetrates therethrough. The second end portion punch hole 77 is located directly below the second end portion punch 73, the shape of the second end portion punch hole 77 is matched with the shape of the second end portion punch 73, and the second end portion punch 73 and the second end portion punch hole 77 are in sliding cooperation, so as to facilitate further cutting of the first interval isolation hole 13 into the second interval isolation hole 14.

[0056] With reference to Figure 2 , Figure 3 and Figure 4 , the bending and punching mechanism 7 further includes an end portion upper punch 75 and an end portion lower punch 76. The end portion upper punch 75 is fixed to the lower surface of the second upper mounting seat 24, and the end portion lower punch 76 is fixed to the upper surface of the lower die plate 33. The end portion lower punch 76 is provided with an end portion punch hole 77 that penetrates therethrough. The shape of the end portion punch hole 77 is matched with the shape of the end portion upper punch 75, so as to process the second end portion isolation hole 15 on the material belt.

[0057] With reference toFigure 2 、 Figure 3 and Figure 5 At the same time, the upper surface of the lower die plate 33 is provided with a second end part blanking hole 334 and an isolation blanking hole 335, the second end part blanking hole 334 is located directly below the second end part punching hole 77, and the second end part blanking hole 334 and the end part punching hole 77 are in communication with each other; the isolation blanking hole 335 is located directly below the end part punching hole 77, and the isolation blanking hole 335 and the end part punching hole 77 are in communication with each other. At the same time, the support seat 32 is also provided with a second belt assembly 37, the second belt assembly 37 conveys waste materials in a second direction, and the second end part blanking hole 334 and the isolation blanking hole 335 are located directly above the second belt assembly 37.

[0058] Referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The bending and punching mechanism 7 realizes complex bending and punching of the workpiece through the precise cooperation of the second upper bending seat 71 and the second lower bending seat 72. The second upper bending seat 71 is fixed to the lower surface of the second upper mounting seat 24, and the lower surface is a curved surface to adapt to the shape requirement of the workpiece after bending; the second lower bending seat 72 is fixed to the upper surface of the lower die plate 33, corresponding to the second upper bending seat 71, and is also a curved surface, which ensures that it can closely fit the workpiece when the mold is closed, realizing accurate bending effect. Not only improves the bending accuracy, but also makes the workpiece force uniform in the bending process, reduces the risk of cracking or deformation caused by stress concentration.

[0059] Continuing to refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 Secondly, the bending and punching mechanism 7 integrates the punching function while bending, further improving the production efficiency. Specifically, the lower surface of the second upper bending seat 71 is fixedly provided with a second end part punch 73, which is in sliding cooperation with the second end part punching hole 77 opened on the second lower bending seat 72, so as to realize the bending of the workpiece at the same time, thereby facilitating the further cutting of the first interval isolation hole 13 into the second interval isolation hole 14. Avoid the secondary processing process of bending first and punching second or punching first and bending second in traditional process, significantly shorten the production cycle, reduce the production cost.

[0060] Continuing to refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5In addition, the bending and punching mechanism 7 also realizes accurate punching of another position of the workpiece through the arrangement of the end upper punch 75 and the end lower punch 76. The end upper punch 75 is fixed to the lower surface of the second upper mounting seat 24, cooperates with the end punching hole 77 opened on the end lower punch 76, ensures accurate penetration of the workpiece during punching, and thus realizes the processing of the second end isolation hole 15 on the material belt.

[0061] Continuing to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the punch and the punching hole in the bending and punching mechanism 7 adopt a special-shaped and front-rear differential height difference structure, so that the punch does not collide with the material belt at the same time during stamping, but contacts the material belt in a certain order, thereby avoiding the one-time and synchronous huge impact force caused by the simultaneous action of all punches. The noise generated during stamping is significantly reduced, the acoustic environment of the workplace is improved, the working mood and communication efficiency of the operators are ensured, and the irreversible damage to the hearing of the operators caused by high noise is also avoided.

[0062] Referring to Figure 2 and Figure 3 , the two-side bending mechanism 8 includes a third upper bending seat 81 and a third lower bending seat 82. The third upper bending seat 81 includes a first positioning block 811 and two upper bending blocks 812, both of which are fixed to the lower surface of the upper die plate 22. The first positioning block 811 is located between the two upper bending blocks 812 and abuts the inner side walls of the two upper bending blocks 812 on both sides, ensuring the stability and positioning accuracy of the workpiece during bending. The height of the first positioning block 811 protruding from the upper die plate 22 is less than the height of the two upper bending blocks 812. The lower surface of the first positioning block 811 is integrally formed with a positioning protrusion 813. The first positioning block 811 and the two upper bending blocks 812 form a bending groove therebetween, and the lower surfaces of the first positioning block 811 and the two upper bending blocks 812 are both curved surfaces.

[0063] Referring to Figure 3 , the third lower bending seat 82 includes a first fixed block 821 and a bending protrusion 822 integrally formed. The first fixed block 821 is fixed to the upper surface of the lower die plate 33 by bolts. The upper surface of the bending protrusion 822 is provided with a first positioning groove 823. The shape of the bending protrusion 822 is matched with the shape of the bending groove. Through the two-side bending mechanism 8, the two sides of the workpiece can be bent. In this embodiment, the number of two-side bending mechanisms 8 is multiple, and the multiple two-side bending mechanisms 8 are arranged in sequence along the length direction of the mold structure, so that the two sides of the workpiece can be bent multiple times, and the two sides of the workpiece can form a complex bending shape, meeting the diversification needs of the accessories.

[0064] Referring to Figure 2 and Figure 3 When the two-side bending mechanism 8 starts to work, the upper die plate 22 drives the third upper bending seat 81 to move downward under the action of the driving device. During the descent of the third upper bending seat 81, the first positioning block 811 first approaches the workpiece, and the positioning protrusions 813 on the lower surface of the first positioning block 811 are inserted into the corresponding positioning holes of the workpiece or are attached to the surface of the workpiece, and at the same time, the two upper bending blocks 812 also approach the workpiece from both sides. Due to the cooperation of the first positioning block 811 and the upper bending block 812 and the action of the positioning protrusions 813, the workpiece is accurately positioned between the third upper bending seat 81 and the third lower bending seat 82.

[0065] Continuing to refer to Figure 2 and Figure 3 As the third upper bending seat 81 continues to move downward, the lower surface curves of the first positioning block 811 and the two upper bending blocks 812 gradually come into contact with the bending protrusions 822 of the third lower bending seat 82. Due to the shape of the bending protrusions 822 being adapted to the bending groove, under the action of the pressure, the workpiece will be bent and deformed along the curved shape of the upper and third lower bending seats 82. A plurality of two-side bending mechanisms 8 are arranged in sequence, and the workpiece will be bent once when passing through each mechanism. Through multiple bending processes, the two sides of the workpiece can form a complex bending shape, thereby meeting the diversified needs of different fittings.

[0066] Referring to Figure 2 and Figure 3 The drilling mechanism 9 includes a second positioning block 91, a top drilling assembly 92, and a side wall drilling assembly 93. The second positioning block 91 is fixed to the upper surface of the second upper mounting seat 24, and the upper surface of the second positioning block 91 is provided with a second positioning groove 911. Meanwhile, the upper surface of the second positioning block 91 is also fixedly provided with a plurality of positioning protrusions 912. When the workpiece is conveyed to the positioning assembly position, the second positioning groove 911 and the plurality of positioning protrusions 912 simultaneously abut against the lower surface of the workpiece, thereby having a positioning effect on the workpiece, ensuring the stability and positioning accuracy of the workpiece during the drilling process.

[0067] The top drilling assembly 92 includes a first mounting block 921, a second mounting block 922, four vertical punches 923, and four clamping blocks 924. The first mounting block 921 and the second mounting block 922 are both fixed to the lower surface of the second upper mounting seat 24. The four vertical punches 923 and the four clamping blocks 924 are arranged in the second direction. The diameters of the four vertical punches 923 can be the same or different, so that the drilling process can simultaneously complete the machining of multiple holes with different diameters, thereby improving the production efficiency. Three of the four vertical punches 923 are fixed to the lower surface of the first mounting block 921, and the other vertical punch 923 is fixed to the lower surface of the second mounting block 922. The top ends of the four vertical punches 923 penetrate through the second upper mounting seat 24.

[0068] Referring to Figure 7 and Figure 8 In the embodiment, the number of clamping blocks 924 is four, and each clamping block 924 is fixed to the lower surface of the second upper mounting seat 24 by a bolt. Specifically, the end of each vertical punch 923 is integrally formed with an anti-disengagement block 925, the lower surface of the first mounting block 921 is fixedly provided with three clamping blocks 924, the lower surface of the second mounting block 922 is fixedly provided with one clamping block 924, the number of clamping blocks 924 corresponds to the number of vertical punches 923 one by one, and each clamping block 924 is provided with an anti-disengagement hole 926 and a through hole 927 that are in communication with each other, and the anti-disengagement hole 926 and the through hole 927 are in communication with each other. The anti-disengagement blocks 925 of the four vertical punches 923 are located in the corresponding anti-disengagement holes 926, and the vertical punches 923 pass through the through holes 927, so as to realize the stable installation and positioning of the vertical punches 923. During the lifting of the upper die 2, the top drilling mechanism 9 drills a plurality of first through holes 16 at the top of the workpiece at the same time.

[0069] Referring to Figure 4 , Figure 6 , Figure 7 and Figure 8 When the top drilling assembly 92 starts to work, the upper die 2 moves up and down under the action of the driving device. During the descent of the upper die 2, the top drilling assembly 92 fixed to the lower surface of the second upper mounting seat 24 also moves downward. As the assembly gradually approaches the workpiece, the four vertical punches 923 will simultaneously contact the top surface of the workpiece. Because the vertical punches 923 are accurately positioned and stably installed, they can accurately drill the workpiece in the vertical direction under the action of pressure. Because the four vertical punches 923 can work at the same time, a plurality of first through holes 16 can be drilled at the top of the workpiece at one time. Moreover, because the diameters of the vertical punches 923 can be different, the diameters of the drilled holes can also be flexibly changed according to requirements.

[0070] Referring to Figure 9 , the side wall drilling assembly 93 includes a transverse drilling piece 931 and a lifting guide piece 932, the transverse drilling piece 931 includes a transverse block 9311 and a horizontal punch 9312, the transverse block 9311 is in sliding cooperation with the second upper mounting seat 24, the horizontal punch 9312 extends in the first direction, and one end of the horizontal punch 9312 is fixedly connected with the side wall of the transverse block 9311. The lifting guide piece 932 includes a second fixed block 9321, two third mounting blocks 9322 and two driving pieces 9323, the second fixed block 9321 is fixed to the lower surface of the upper die 2 plate, and the two third mounting blocks 9322 are both fixed to the lower surface of the upper die 2 plate. The two driving pieces 9323 are respectively fixed to the side walls of the two third mounting blocks 9322 that are away from each other.

[0071] Referring toFigure 9 and Figure 10 Specifically, each driving piece 9323 comprises an integrally formed connecting block 93231 and a driving block 93232. The connecting block 93231 is fixed to the side wall of the third mounting block 9322. The two ends of the traversing block 9311 are provided with inclined driving grooves 9313. The top end of the driving groove 9313 is open, and the bottom end of the driving groove 9313 is closed. The driving block 93232 is located in the driving groove 9313, and the driving block 93232 is in sliding fit with the driving groove 9313, so as to process the second through hole 17 in the side wall of the workpiece.

[0072] Referring to Figure 9 and Figure 10 When the side wall drilling assembly 93 starts to work, the upper die 2 plate performs lifting movement under the action of the driving device. Since the second fixing block 9321 and the third mounting block 9322 are both fixed to the lower surface of the upper die 2 plate, they will move together with the upper die 2 plate. During the descending process of the upper die 2 plate, the driving piece 9323 fixed to the side wall of the third mounting block 9322 also descends. The driving block 93232 on the driving piece 9323 enters the inclined driving groove 9313 at the two ends of the traversing block 9311. With the continuous descent of the driving piece 9323, the driving block 93232 slides in the driving groove 9313. Since the driving groove 9313 is inclined, the sliding movement of the driving block 93232 will generate a horizontal component force on the traversing block 9311, thereby pushing the traversing block 9311 to move horizontally on the second upper mounting seat 24. When the traversing block 9311 moves, the horizontal punch 9312 fixed to the side wall thereof also moves. When the horizontal punch 9312 contacts the side wall of the workpiece, under the action of the continuous pressure, the horizontal punch 9312 will process the second through hole 17 in the side wall of the workpiece. Through the lifting movement of the upper die 2 plate, combined with the special matching structure of the driving piece 9323 and the traversing block 9311, the horizontal movement and drilling operation of the horizontal punch 9312 are realized, thereby completing the task of processing the second through hole 17 in the side wall of the workpiece. The whole process relies on the accurate matching and movement conversion between the components, ensuring the accuracy and stability of the drilling.

[0073] Referring to Figure 2 , Figure 3 and Figure 5The cutting mechanism 10 includes a clamping assembly 101 and a cutter 102. The clamping assembly 101 includes a lower clamping block 1011, an upper clamping block 1012, and a positioning column 1013. The lower clamping block 1011 is fixed to the upper surface of the lower template 33. A sliding hole 1014 extending in the vertical direction is formed on the upper surface of the lower clamping block 1011. The axis of the sliding hole 1014 coincides with the axis of the positioning column 1013, and the positioning column 1013 can slide and fit in the sliding hole 1014. The upper clamping block 1012 is fixed to the lower surface of the second upper mounting seat 24. The cutter 102 is also fixed to the lower surface of the second upper mounting seat 24 and is located on one side of the upper clamping block 1012. A side material blanking hole 336 is formed on the upper surface of the lower template 33 at the position corresponding to the cutter 102. The cutter 102 slides and fits in the side material blanking hole 336. In addition, a second inclined material removal track 337 is fixedly provided at the end of the lower template 33, and the top end of the second material removal track 337 is located below the cutting mechanism 10. A third belt assembly 38 is also provided on the upper surface of the bottom plate 31, and the third belt assembly 38 is located directly below the edge material drop hole 336, which is used to transport the edge material waste generated by the second punching mechanism 5 along the second direction.

[0074] Continue to refer to Figure 2 、 Figure 3 and Figure 5 When the upper die 2 begins to descend, it drives the upper clamping block 1012, the positioning post 1013, and the cutter 102 to move downward together. The upper clamping block 1012 and the lower clamping block 1011 cooperate with each other to clamp the workpiece placed between them, preventing the workpiece from moving freely during the processing. At the same time, the positioning post 1013 passes through one of the first through holes 16 on the workpiece and the sliding hole 1014 on the lower clamping block 1011 in sequence, thereby accurately determining the position of the workpiece. The positioning function of the positioning post 1013, combined with the clamping function of the upper and lower clamping blocks 1011, achieves a firm positioning of the workpiece, providing a stable foundation for subsequent cutting operations.

[0075] Continue to refer to Figure 2 、 Figure 3 and Figure 5 After the workpiece is successfully positioned and clamped, the cutter 102 continues to descend with the upper die 2 until it cuts into the edge material blanking hole 336 on the upper surface of the lower die plate 33. As the cutter 102 cuts into the workpiece, the edge material waste will fall through the edge material blanking hole 336, and the cut workpiece will slide down the inclined second blanking track 337, completing the blanking process.

[0076] It is worth noting that in the present embodiment, the ends of the intermediate punch 41, the first end punch 42, the first communication punch 51, the first upper bending seat 61, the first lower bending seat 62, the second upper bending seat 71, the second lower bending seat 72, the third upper bending seat 81 and the third lower bending seat 82 are all curved, with a height difference between front and back, so that the punches can produce a time difference between front and back during stamping. The beneficial effects brought by this are that it effectively avoids the excessive noise caused by all punches impacting the material belt 1 at the same time, reduces the noise pollution during mold stamping, improves the working environment, and at the same time, to a certain extent, reduces the damage to the mold and the material belt 1 caused by excessive instantaneous impact force, helps to improve the service life of the mold and the quality stability of the stamped products.

[0077] The implementation principle of the above embodiment is that after the metal coil material is flattened, it is conveyed from one end of the mold to the other end under the power drive, and each part of the mold successively stamps the coil material, and finally completely stamps into the shape of a fitting. During the stamping process, the first punching mechanism 4 and the second punching mechanism 5 realize the punching of the hole, the initial bending mechanism 6, the bending punching mechanism 7 and the two side bending mechanisms 8 realize the bending of the workpiece, the drilling mechanism realizes the drilling of the top and side wall of the workpiece, and finally the cutting mechanism cuts the completed workpiece from the coil material. The entire continuous lower die 3 has a reasonable layout and close cooperation between each mechanism, ensuring the efficiency and accuracy of the stamping process. At the same time, through the first belt assembly 35, the second belt assembly and the third belt assembly, the waste material is transported and processed in a timely manner, avoiding the impact of the accumulation of waste material on the mold. In addition, the use of special-shaped punches, height differences between front and back, and other structures in the mold reduces noise, further improving the comfort and life of the mold.

[0078] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made in accordance with the structure, shape, principle of the present application should be covered within the protection scope of the present application.
